Patent GB-928566-A (GB)
Title: Lightning arrester
IPC: H01T1/14
Filed: 1961-09-25
Abstract: 928,566. Lightning arresters. WESTING- HOUSE ELECTRIC CORPORATION. Sept. 25, 1961 [Nov. 14, 1960 (2)], No. 34186/61. Class 38 (4). In a lightning arrester comprising a plurality of spark gaps and valve blocks disposed in a housing closed at opposite ends by rupturable diaphragms, the blocks are protected against excessive current causing gas generation and consequent explosion of the arrester housing by a pair of electrodes mounted at the ends of an open-ended passage, and a current sensitive means effecting ionization of the space between the electrodes establishing a low-resistance path in parallel with the block, the increased pressure resulting from conduction across the space being relieved through the ends of the passage, causing the diaphragms to be ruptured. A lightning arrester comprises 3 columns mounted in the foil formation and connected in series, each column comprising two units having any number of known value blocks and spark gaps in series. The units have a central passage closed by a plug carrying current-sensitive elements 62, 64, 66 which comprise a pair of substantially cylindrical hollow electrodes 70, 72 connected by a fusible wire 74 carried by an insulating tube 68. The outer electrode 72 is in contact with a conducting bushing 78 which carries a conical hammer 80 which may be of metal. When the temperature of the arrester rises through prolonged power follow current through the valve blocks, the wires 74 and vaporized generating ionised gases and the top and bottom bushings will arc across causing current to be diverted away from the valve blocks and simultaneously generating a pressure wave which will eject the hammers through the diaphragms allowing relief of the internal pressure. The ionised gases are then directed by means of end fittings (not shown) across the outside of the arrester thus transferring the arc from inside the arrester. The hammers may be replaced by springs which place a preload on the diaphragms so that an increase in pressure ruptures them.

Title: Electric timepiece with chronograph indicator
IPC: G04C3/06
Filed: 1971-07-23
Abstract: 1349974 Electronic timepieces EBAUCHES S A 23 July 1971 [7 Aug 1970] 34676/71 Heading G3T In an electronic timepiece functioning both to indicate the time of day and as a chronograph, a drive circuit for the timepiece balance wheel transducer is modified automatically when the chronograph section is turned ON in order to compensate for the extra power required to drive the chronograph indicator and maintain the amplitude of oscillation of the balance wheel unchanged. In Fig. 2, pick-up and drive coils 12, 13 respectively, co-operate with magnets 10, 11 on a balance wheel 9. When the chronograph indication is to be used a push piece (7) is manually operated thereby closing a switch 19 which connects a resistor 18 in parallel with a time constant circuit C16 R17. This alters the bias of a drive transistor 15 so that stronger drive current pulses are applied to coil 13. In a modification Fig. 3, (not shown), there are two pick-up coils the second of which is switched in when chronograph operation is required. In a similar arrangement Fig. 4, (not shown), second drive coil is switched in. In an embodiment Fig. 5, (not shown), one coil serves as both drive and pick-up, and there are two transistors one serving as a drive and the other as a control transistor.

Abstract: 393,992. Printing-machines. SCHNELLPRESSENFABRIK FRANKENTHAL ALBERT ET CIE AKT.-GES., Frankenthal, Pfalz, Germany. Dec. 17, 1931, No. 34953. Convention date, April 20. [Class 100 (ii).] Rotary intaglio machines.-Relates to a rotary machine of the kind in which two or more printing-couples B, C are arranged in tandem and are provided with feed piles 1, 3 and delivery piles 2, 4, so that separate sheets may be printed by each couple, or alternatively the printed sheet from the couple B may be fed by a conveyer device 16 to the second couple C so as to receive a multiple impression on one side. According to the invention, a sheet-removing device 20 may be put into action if desired so as to cause the couple C to perfect the sheet printed by the couple B. Additional couples may be used so that the machine may print more than two colours on one side of a sheet, or may print perfected impressions with one alone on one side and several on the other, or with two colours on each side. Normally the sheets are taken from the impression cylinder 7 of couple B by means of chains 10, driven at the same speed as the couple B, and a transfer cylinder 11 transfers the sheet to grippers 13 on chains 12 driven at half the speed of the chains 10. The chains 12 can either deliver the sheet to a pile 2 or to a conveying device 16 which forwards the sheet to the couple C directly, or after the sheet has been reversed by the device 20 which comprises a chain-and-gripper device driven at the same speed as the chains 12. The delivery device 16 comprises a horizontal conveyer 18 and pivoted conveyers 17, 19, which can be swung into vertical positions out of action, and the reversing device 20 may be thrown out of gear and raised to the inoperative position shown by dotted lines.

Title: Flexible conduits
IPC: B29D23/18
Filed: 1958-10-31
Abstract: 855,364. Flexible conduits. DAYCO CORPORATION, [formerly DAYTON RUBBER CO.]. Oct. 31, 1958 [Nov. 25, 1957], No. 35054/58. Class 99(2). In a flexible, fluid-impervious conduit, a helical coil of plastic or rubber coated wire 12 is surrounded and elastically embraced by a first elastomeric sheath 14 which is itself surrounded by a second coextensive elastomeric sheath 15 in partial elastically embracing contact with the sheath 14 and otherwise closely spaced therefrom. As shown, the sheath 14 consists of a corrugated tube having the crests 17 thereof fused to the turns of the coil 12 and in elastic contact with the crests 17a of a corrugated tube forming the sheath 15, the troughs 16, 16a of the sheaths 14, 15 being spaced from each other by a narrow air space 18. More than one additional sheath may surround the sheath 14, each being spaced from the other by an air space. The wire 12 is coated with plastic by passing through an extruder and the sheaths 14, 15 are formed by extrusion. The material for coating the wire 12 and of which the sheaths are made may be natural or synthetic rubber, polyamides, polyethylene, polyvinyl chloride, polyvinyl acetate, vinylidene chloride or a polyurethane. In making the conduit the sheath 14 is expanded in a vacuum expander box and the coil 12 previously tensioned is inserted in the sheath which is then allowed to contract over the coil. Fusion of the plastic coating of the coil with the sheath 14 is then obtained by passing electric current through the coil. The sheath 14 with the coil therein is then introduced in the sheath 15 which is similarly expanded in a vacuum expander and then allowed to contract over the sheath 14.
